IMPROVEMENT lN SASH-HOLDERS.

SPEoIFIcA'rIoN.

Be it known that L'HENRY W. BAKER, of Burlington, county of Mineral,State of West Virginia, have invented a new and Improved Sash-Holder andLock; and I declare the following to be a full, clear, and exactdescription of same, such as will enable others skilled in the art towhich it pertains to make and use it, reference being had to theaccompanyin g drawing which forms a part of this speci- Iication.

My invention relates to a secure sash-holder which will always catch,and it is simple and strongin its construction and consists informing,in connection with this sash-holder, a convenient locking device forsecuring the window when closed, as will be hereafter more fullydescribed.

I n the drawing, Figure 1 is a view of the sash-holder as applied to theupper frame. B is the window-frame B', the groove in which the sash Aslides. D is the metal piece or block which holds the latch or pawl E. eis a shoulder, which strikes against the bed-plate D. F His thethumb-piece to unloosen the latch. At the lower part of Fig. 1 is lowersash-holder, differing from the upper by the curved thumb-piece. L isthe locking-do g, set e 1s a shoulder, which strikes against the liangem.

Fig. 2 is a sectional view, in elevation, of

the sash-holder with the recesses or ratchets E in the sash. U is themiddle strip, shown in Fig. 1, the dotted lines representing thethumb-piece or lever, set into the middle strip C so as to be clear ofthe lower sash when the latter is raised. e is the shoulder.

Fig. 3 is sectional view of the sash A, showing metal recesses orratchets.

Fig. 4 is view of the latch in isometrical projection, with a portion ofthe bed-plate removed so as to expose the latch. The full linesrepresent the upper, and the full and dotted lines the lower,sash-holders.

I form the bed-plate D of a piece of metal providedwith arecess formedinto and through it, as shown in the drawing. This recess is so shapedthat when the latch is pressed back into it the whole surface presentedto the sash will be Hush or smooth. The bottom part is formed with abevel extending part of the distance back, as shown in Fig. 2, so thatthe shoulder e of the latch may rest dat upon it when supporting' theweight of the sash, and thus throw no strain upon the pivot. This blockis sustained to the frame by a screw near its bottom end. The latch orpawl is formed of one piece of metal, with an upright piece, E, atransverse bar, G, to carry it clear of the sash, and two arms, H and F.The whole is retained in 'the bed-plate by a pivot which passes througha heel, J, which projects back beyond the balance of the latch, thusthrowing its cent-er of gravity toward the sash that it may always fallinto the recesses or ratchet. The sash is provided with recesses orratchets E, which may be oi' metal, or may be simply cut into the sash.The upper sashholder9 is so arranged that the thumb-lever will liewholly within the middle strip of the frame, so as to be out ofthe wayof the lower sash and of the strip it carries on its upper edge. Thelower sash-holder is provided with a curved thumb-piece, F', under whichthe locking dog or bar L may fall, and thus secure the Window whenclosed. This locking-dog L is preferably set into a bed-plate with aflange, m, so that, when resting beneath the latch F',

its shoulder e rests solidly against the flange,

vided with the curved thumb-latch F, in combination with the locking-dogL with or without bed-plate and ange m, whereby a sash is securelylocked in position, all substantially as described and shown, for thepurposes set forth.
